When using the `sis-sqlstore` datastore upon a PostGIS table with a geometry column,
if a bbox filter is applied on a FeatureSet, its conversion to an SQL clause for it ignore any CRS information. In this case, the resulting clause is wrong, apart for the case where the CRS is already aligned.
We must at least try to write geometry SRID when possible (so, use [EWKT format|https://postgis.net/docs/ST_GeomFromEWKT.html).]
Otherwise, when we can determine a common CRS in advance (most likely the one of the implied geometry column for optimisation purpose), we could try to reproject before-hand the literal filter (if any).
